路由守卫相关学习

路由守卫可以在路由跳转处进行检查，未达到要求不予跳转

const router = new Router({
  {path:'/',name:'test1',component:test1},
  {path:'/home',name:'home',component:home},
  {path:'/login',name:'Login',component:login},

})


router.beforeEach((to,from,next)=>{


if(to.path=='/login'){
  next()  //next() 相当于1个开关，允许跳转
}else{
if(判断条件){
next()
}else{
next({path:'/login'})
}
}


})
export default router  //切记暴露router
